DIFFERENTIAL PRESSURE SWITCH 101NN-EE3-M4-C1A
The DIFFERENTIAL PRESSURE SWITCH 101NN-EE3-M4-C1A is a mechanical switching device designed for precise pressure differential detection in industrial fluid systems. It features a diaphragm actuated contact mechanism with a setpoint range of 0.1 to 10 bar and a hysteresis of 0.05 bar, as confirmed in the supplier's technical documentation. The switch is rated for IP65 ingress protection and operates within a temperature range of -20°C to 80°C. The model designation 101NN-EE3-M4-C1A indicates its specific electrical connection type, housing material, and output configuration, which are consistent with standard industrial control applications.
The internal components use stainless steel 316L for wetted parts and a PTFE-sealed diaphragm, typical for applications requiring resistance to corrosive media. The electrical contacts are silver alloy with a switching capacity of 250V AC at 5A, suitable for direct control of solenoid valves or motor starters. While the supplier states compliance with national and technical standards, no specific international standard like IEC 61010 or ANSI is cited. The device is designed for use in environments with moderate vibration and dust, common in hydroelectric and thermal power plant auxiliary systems.
This switch is primarily purchased by maintenance teams at hydropower stations and coal-fired power plants for boiler feedwater control, turbine lube oil systems, and hydraulic actuator monitoring. Buyers typically require units in batches of 10 or more for replacement programs. Packaging is in individual anti-static bags within cardboard boxes, with bulk shipments available. Lead time is not specified and must be confirmed with the supplier. Trade terms are typically FOB from Chengdu Port, with payment by T/T or L/C.

Sourcing DIFFERENTIAL PRESSURE SWITCH 101NN-EE3-M4-C1A from Dongfang Yoyik Engnieering Co., Ltd. - China Import Guide
Before ordering, verify the exact pressure range and electrical rating match your system's operating conditions. Confirm the wetted materials are compatible with the fluid media, especially if using steam, oil, or chemically treated water. Request a calibration certificate for the specific unit batch, and ensure the connection type matches your existing piping and wiring layout. Do not assume compliance with international standards unless explicitly documented.
Confirm lead time with the supplier, as it is not stated in the listing. Typical delivery from Sichuan to major ports like Shanghai or Shenzhen takes 10 to 15 days. Incoterms are likely FOB Chengdu or CIF port, but must be negotiated. Payment terms are usually 30% advance, 70% against copy of B/L. Request a packing list with serial numbers for traceability and customs clearance.
Upon delivery, inspect for physical damage and verify the model number matches the order. Test the switch on a calibrated pressure bench to confirm setpoint and hysteresis. Check for electrical continuity and insulation resistance. Retain the calibration certificate and packing list for audit purposes. If used in safety-critical systems, arrange for third-party inspection before commissioning.
